----------------------------Original message---------------------------- Greg, Our plan is similar to yours, with a couple cruseifications: shelve census maps in Docs stacks. Shelve Thomas Bros.' county street atlases, census editions, in Docs Ref. We're buying all the CA metro counties. THEN, we're trying to get the census tract maps done by each county's planning dept. These we laminate, including a tattle tape. These can be folded as necessary (shelve next to Thomas Bros.?). We have the San Diego version posted on a piller in the middle of Docs Ref. This is the one students photocopy from because local planners have superimposed neighborhood and regional economic area boundaries on appropriate tract groupings. Also, "SANDAG" has reconfigured the data to match their map nesting arrangement. I assume that SCAG has done something similar for the remaining SoCal counties. AND, I'll bet there's equivalent SMSA mapping done for the rest of the U.S. Would make a great list if everybod pitched in and sent info on their county planning dept. equivalent census tract map to you and you compiled a list, including cost, if any. Let me know if you're willing. By these means, I'm hoping that our GPO tract maps will hardly ever be used, won't need preservation treatment and won't be stolen. [log in to unmask] At CSU-Long Beach, we have our 1990 Census of Population and Housing Tract and Block maps in open government document stacks, arranged by sudoc. They are folded in their original white and green envelopes. I am looking for ways to make at least the Los Angeles and Long Beach maps more durable. I am considering "Chartexing" them, folding them accordion-style to 1/3 their original size, and binding every 5 sheets with three or four key-ring holders at the edge. By using this method, the maps would still be flexible and maneuverable for photocopying. Does anyone have any other ideas? I do not have the option of enclosing them behind a service point or into the map collection. Any other conservation methods employed out there? Thanks.
